So my citalopram stopped working after about 15 years, I'd slowly gone up to the highest dose. I've been put on fluoxetine and have been on it for 3 weeks now. I had been suffering really bad panic attacks and anxiety when I switched meds. The forst week wasn't great but started to feel like they were having an effect by week 2. Week 3 I've slowly gotten worse and anxiety and panic attacks have come back with a bang 🙈 can anyone reassure me that they will eventually take effect? Or does it sound like they aren't working for me?
